MACHINE.

SPECIFICATION forming part of Letters Patent No. 235,096, dated December7, 1880.

Application filed December 8, 1879.

To all 'whom it may concern Be it known that 1, CHARLEs H. MILLER, ofErie, in the county of Erie and State of Pennsylvania, have invented anew and useful Improvement in wringing-Machines, of which the followingis a specification, reference being had to the accompanying drawings.

This invention relates more particularly to a wringing-machine fordomestic purposes,

1o and has for its object to render the machine simple, durable, andcompact.

My invention consists or" a wringing-machine having an upper stationaryroller and a lower movable roller, which is rendered selfadjusting bymeans of a spring of peculiar construction arranged between the lowerportions of the side frame of the machine; also, of sliding bearings inwhich the movable roller is supported, and which are provided with exzotensions having concave ends, which bear against the shaft of thestationary1 roller when the machine is not in use, whereby the rollersare held in such a position as to prevent the spring from exerting anypressure upon the 2 5 contiguous portions of the rollers when not inuse; also, of a peculiar construction of the spring whereby the latteris rendered more durable and prevented from being lengthened bycompression.

In the accompanying drawings, Figure l is a partly sectional frontelevation of my improved wringing-machine. Fig. 2 is a crosssectionthereof. Fig. 3 is an end elevation thereof. Fig. 4 is a perspectiveview of one of the bearings of the movable roller.

Like letters of reference designate like parts in the several figures.

A A represent the side frames of the machine, which are securelyconnected by a tierod, b, and the inclined plate or table c. D

represents the upper stationary roller turning in fixed bearings formedin the upper ends of the side frames, A A. E is thelower movable roller,having its shaft f supported in sliding 4 5 bearings G G, arrangedinrecesses or depressions g on the inner sides of the side frames, A A. His an upward extension formed with each bearing G, and made of suchlength that the upper end of the extension H will come 5o in contactwith the shaft of the upper stationary roller and arrest the upwardmovement of the lower movable roller when the two rollers are about incontact with each other. t' are vertical slots formed in the sideframes, A A, to permit the vertical movement of the shaft of the lowerroller, E. is 7c are two lugs formed on the lower end of each bearing G,so as to form a recess or socket for the reception ofthe ends of theupper bar of the spring L.- The latter is composed of two flat bars bentso as to converge from their distended ends toward the middle.

Each bar is bent back or indented at the middle,so as to form two convexbearing-surfaces, m m, by which the two bars come in contact with eachother. The ends of the lower spring-bar rest upon the bottom of therecesses g of the side frames, and the ends of the upper bar restagainst the lower ends of the bearings G, between the lugs k thereof.

When the machine is not in use the extensions H of the bearingsl G restagainst the shaft of the upper roller, D, and prevent the spring frompressing the lower roller against the upper roller, thereby avoiding theHattening of the rollers, which always takes place to a greater or lessextent when this pressure is not relieved.

Upon introducing the garments or other articles between the rollers thelatter are forced apart and the distended ends of the spring L arecompressed. As the distended ends of the springs approach each other thecentral bent portions of the spring-bars are distended, thereby avoidingthe lengthening ofthe springs by compression, which takes place inordinary springs. This peculiar construction of the springs renders thesame also more powerful and more durable, thereby rendering an adjusting device unnecessary and permitting the spring to be located between thelower portions of the side frames, which portions form one of the jawsby which the machine is secured to a tub or other vessel or support.

I claim as my inventionl. In a wringingmachine, the combination, withthe side frames, A A, of the upper roller, D, supported in fixedbearings, the lower roller, E, supported in movable bearings G, and thespring L, constructed with convex bearin g roo surfaces m, and havingits distended endsI arranged in the recesses g of the side frames, belowthe lower roller, substantially as set forth.

2. In awringing-inachine, the combination, with the side frames, A A,provided with recesses g, fixed roller D, and movable roller E, of thesliding bearings G, provided with eXtensions H, having concave endsadapted to come in contact with the shaft of the fixed roller before thesurfaces of the two rollers touch each other, thereby preventing therollers from being pressed against each other when the machine is notbeing used, and avoiding the flattening of the rollers, substantially as4set forth. V

3. The spring L, composed of two at bars having distended ends, andhaving their middle portions bent back or indented to form two convexbearing-surfaces, m m, by which the two bars bear upon each other,substantially 2o' as set forth.
